Olivine has a hardness of 6.5 to 7 on the Mohs scale. This places it in the range of moderately hard minerals, making it more resistant to scratching than softer minerals like calcite but less so than harder ones like quartz. Its hardness contributes to its durability in various geological environments, where it can be found in igneous and metamorphic rocks.

What are three most useful properties of identification for olivine?
Olivine has a distinctive green color, making it easy to identify visually. It has a high hardness of 6.5-7 on the Mohs scale, aiding in its differentiation from other minerals. Olivine often occurs in tabular or elongate crystal shapes, which can help distinguish it from similar minerals.
What is a non-vesicular rock that is made entirely of green 2 mm diameter crystals that have a hardness of 6.5 and show fracture?
The rock you are describing is likely a type of peridotite, specifically composed of olivine crystals. Olivine is commonly green, has a hardness of around 6.5 on the Mohs scale, and can exhibit a conchoidal fracture. This non-vesicular rock typically forms in ultramafic igneous environments, such as the Earth's mantle.
What type of luster does olivine have?
Olivine typically exhibits a glassy or vitreous luster. This is due to its composition of magnesium, iron, and silicate minerals, which create a smooth, reflective surface when light interacts with the crystal structure. The luster of olivine can vary depending on the specific composition and crystal structure of the mineral.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.
What mineral group does Olivine belong to?
willemite
What mineral scratches dolomite but it scratched by olivine?
Quartz scratches dolomite but is scratched by olivine. Dolomite has a Mohs hardness of 3.5-4, while quartz has a hardness of 7. Olivine, on the other hand, has a higher hardness of 6.5-7.
What are 3 properties or olivine?
Olivine is a nonmetallic mineral with a hardness on the Mohs Hardness Scale of 7. It has a white streak and its color is pale or dark olive-green to yellow, or brown. It forms short crystals that may resemble sand grains. Also, it has a conchoidal fracture and has no cleavage. It is brittle and has a specific gravity of 3.3 to 3.4.

Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
